The present research is carried out to
determine the automatic coordination of
Inverse Definite Minimum Time Overcurrent
relays for distribution networks.
The proposed algorithms are developed in
MATLAB and PowerFactory, which are
focused to avoid the total disconnection of
customers to the main grid, improving
resilience and the recovery capacity of the
distribution system during disturbances.
The initial study case contemplates a
preliminary protection coordination in
PowerFactory for a distribution network,
which is affected by an external event,
producing an aleatory change into
topology grid due to loss of the electrical
components in the distribution network.
Consequently, based on short circuit
analysis is possible to calculate
automatically the current setting values
(Pickup current) and time dial or Time
Multiplier Setting (TMS) for each relay.
The aforementioned procedure ensures
that system maintain continuity of service
in no-affected zones, preventing the total
outage of distribution system as a result of
absence of coordination of protection or
by improper coordination of protections. |
